5 Basit Teknikleri için Telgraf kim icat etti

Morse code saf been in use for more than 160 years—longer than any other electrical coding system. What is called Morse code today is actually somewhat different from what was originally developed by Vail and Morse. The çağdaş International Morse code, or continental code, was created by Friedrich Clemens Gerke in 1848 and initially used for telegraphy between Hamburg and Cuxhaven in Germany. Gerke changed nearly half of the alphabet and all of the numerals, providing the foundation for the modern form of the code.

The Morse system for telegraphy, which was first used in about 1844, was designed to make indentations on a paper tape when electric currents were received. Morse's original telegraph receiver used a mechanical clockwork to move a paper tape. When an electrical current was received, an electromagnet engaged an armature that pushed a stylus onto the moving paper tape, making an indentation on the tape. When the current was interrupted, a spring retracted the stylus and that portion of the moving tape remained unmarked. Morse code was developed so that operators could translate the indentations marked on the paper tape into text messages.

When Morse code was adapted to radio communication, the dots and dashes were sent kakım short and long tone pulses. It was later found that people become more proficient at receiving Morse code when it is taught birli a language that is heard, instead of one read from a page.[17]

Morse had formulated the rudiments of the telegraphic alphabet, or Morse Code, kakım it is known today. He was incele ready to sınav his invention.
